Since the angle 170° 170 ° is in the second quadrant, subtract 170° 170 ° from 180° 180 °. 180°− 170° 180 ° - 170 °. Subtract 170 170 from 180 180. 10° 10 °. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step ... Terminal side is in the third quadrant. When the terminal side is in the third quadrant (angles from 180° to 270° or from π to 3π/4), our reference angle is our given angle minus 180°. So, you can use this formula. Reference angle° = 180 - angle. For example: The reference angle of 190 is 190 - 180 = 10°. When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Reference angle° = 180 - angle. Thus, the reference angle of 170° = 180 - 170 = 10°. Important: the angle unit is set to degrees.reference angle. 9. 2 3S J The angle J is on the positive y-axis. Thus, the angle J does not have a reference angle. Back to Topics List 2. THE REFERENCE ANGLE OF THE SPECIAL ANGLES The reference angle of the Special Angles of , 6 7, 6 5, 6 S S S r r r and 11S r is 6 S. The reference angle of the Special Angles of , 4 5, 4 3, 4 S S S r r r and ... Reference Angles. Examples, solutions, videos, worksheets, games, and activities to help Algebra 2 students learn about reference angles. To find the value of sine and cosine at non-acute angles (from 90 to 360), first draw the angle on the unit circle and find the reference angle. A reference angle is formed by the terminal side and the x-axis ...Trigonometry. Find the Reference Angle 660 degrees. 660° 660 °. Find an angle that is positive, less than 360° 360 °, and coterminal with 660° 660 °. Tap for more steps... 300° 300 °. Since the angle 300° 300 ° is in the fourth quadrant, subtract 300° 300 ° from 360° 360 °. 360°− 300° 360 ° - 300 °. Subtract 300 300 from 360 ... Netflix's live-action "Avatar: The Last Airbender" adapts the original cartoon, and has plenty of easter eggs. They include recreations of shots from the cartoon and …Find an angle that is positive, less than 360° 360 °, and coterminal with 480° 480 °. Tap for more steps... 120° 120 °. Since the angle 120° 120 ° is in the second quadrant, subtract 120° 120 ° from 180° 180 °. 180°− 120° 180 ° - 120 °. Subtract 120 120 from 180 180. 60° 60 °.Netflix's live-action "Avatar: The Last Airbender" adapts the original cartoon, and has plenty of easter eggs. They include recreations of shots from the cartoon and …The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. So, the reference angle of 67.5° = 67.5°. Important: the angle unit is set to degrees..

The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Thus, the reference angle of 143° = 180 - 143 = 37°.
